Digital video communication system and method facilitate conservation of communication bandwidth are presented. A present invention method forwards sampled chrominance data to other components in the system. Pixel chrominance values are sampled in accordance with the sampling scheme. The sampled chrominance values (e.g., 422, 420, 411, etc.) are forwarded to another component. For example, a graphics processing unit performs sampling operations and forwards the chrominance sampled information to another component (e.g., a board, a display, etc.). The graphics processing unit can also perform color space conversion before forwarding the chrominance sampled information to the other component. The other component performs up-sampling. For example, a display can perform the up-sampling to generate synthesized full RGB values. The sampled chrominance data can be further compressed (e.g., MPEG, WMV, etc.) before forwarding the sampled chrominance data and before performing the up-sampling.
